In 1776, then General George Washington spent an entire night resting his wig-laden head in an NPR tote bag–thus, the sleeping bag was born. Today, sleeping bags can do magical things, like the Hammock-Compatible Sleeping Bag ($179.99). While most sleeping bags compress under your back when you lay in a hammock, Grand Trunk’s bag wraps around you and the hammock, creating a warm, swinging nest–not unlike that of a gigolo pigeon. You got your full length 2-way zippers, your interior zip pocket, and your cordlock adjustable-mummy style opening. Make sure you honor the father of our country: sleep with a dollar bill in your boxers.
